Just over a year after a chemical spill endangered the drinking water supply of 300,000 people in West Virginia, state lawmakers are scaling back regulations designed to protect the water supply from leaky storage tanks.

When the Jacksonville, Florida Naval Air Station needed to increase oxygen in their aeration basins, they turned to RWL Water. Five submersible HURRICANE aerators provide bottom-up mixing, drawing surface air and dispersing it in a 360-degree pattern near the basin floor. Long bubble hang time results in excellent oxygen transfer, and ensures excellent BOD and ammonia removal, treating flows up to 3 MGD.

According to the American Water Works Association (AWWA), the North American drinking water infrastructure network spans about one million miles, which is more than four times the length of the National Highway System.

In the dicey world of water politics, unusual allegiances sometimes crop up. Just this month, Israeli leaders indicated that they have plans to increase the amount of water they send to the Gaza Strip.

Grit settling velocity is significantly impacted by variability in size, density and shape. The conventional assumption of spheres with a specific gravity of 2.65 is inadequate for characterizing grit.

Xylem TotalCare Condition Audit, an inspection and recommendation program that helps plant operators find ways to lower maintenance costs by identifying inefficiencies in the operation of water and wastewater equipment, was elected to audit the American Canyon Wastewater Treatment Plant (WWTP) in Calirfornia.

The impact of preliminary treatment (i.e., grit removal, screening, washing compacting of screenings, handling of screenings, and resource recovery) on downstream processes is becoming more apparent as the industry looks for ways to reduce operating costs and increase process results.

The City of Chester, IL was getting only about 6 months life out of the mechanical seals in their former non-clog lift station pumps. While replacing seals twice per year was difficult and expensive, the more serious problem occurred when the seals failed with the Mississippi River at flood stage and with the sealed lift station underwater.

Together, two water treatment plants in Boulder, CO, have the capacity to treat 55 million gallons per day (MGD). When severe drought conditions restricted the source water supply of the Betasso WTP, the city decided to expand the capacity of the Boulder Reservoir Water Treatment Plant (WTP).

Veolia's HPD® Crystallization Technology will be an essential part of the first greenfield project in North America in nearly 40 years when completed in 2016. The Legacy Project will produce 2 million tonnes per year of potassium chloride by 2017.

The Sni-A-Bar Wastewater Treatment Plant (WWTP) serves the nearby cities of Blue Springs and Grain Valley, MO. In 2013, the city of Blue Springs completed an expansion project to increase plant capacity and improve effluent discharge, allowing the Sni-A-Bar WWTP to meet more stringent environmental requirements mandated by the EPA and the Missouri Department of Natural Resources (MDNR).

Faced with a tight capital budget, a city in British Columbia required a new design for a water treatment plant capable of a maximum daily water production of 21 MPG during peak demand periods, with an ultimate demand of 29 MGD.

The successful addition of new restaurants and clubs at a resort and casino in Upstate NY brought with them a flow of fats, oil and grease (FOG), which gelled into a floating blanket atop the main station’s wet well, where the sewage flows converge from the network of smaller stations throughout the property boundaries.

In the past, a lift station operation in Ohio had to send crews out daily to unclog one or more pump stations in the county service area. Chronic blockages were attributed to pump design, byproduct grease from restaurants, and medical waste from assisted living and nursing homes along the lines.

Badger Meter, a leading global innovator and manufacturer of flow measurement and control solutions, today announced it will be the Platinum Sponsor of the American Water Works Association (AWWA) Annual Conference and Exposition (ACE15), which will be held in Anaheim Calif., June 7-10.

Hach Company, a Loveland-based company that designs and manufactures water quality analysis equipment sold across the globe, is hosting the 2nd Annual Hach Walk for Water on May 2nd from 9am to 12pm at Loveland High School to benefit Water Missions International.

Ovivo announced recently that they have been awarded the contract by Siemens to provide engineering, fabrication, documentation, mechanical and electrical erection, commissioning and training of a Demineralization plant at the Plock Petrochemical plant in Poland.

OriginOil Inc., developer of Electro Water Separation (EWS), the high-speed, primarily chemical-free process to clean up large quantities of water, announced recently the launch of its OriginClear product line for all waste water treatment, including oil and gas water cleanup.

The Natural Resources Consulting Engineers, Inc. (NRCE) and CH2M HILL are pleased to announce they have been awarded a contract to provide engineering and technical support services to the U.S. Agency for International Development’s (USAID) Missions, Bureaus and Offices worldwide in the implementation of the Agency’s Water and Development Strategy.

Over the past several decades, activated carbon has proven to be a reliable, cost-effective technology for the control of various odorous compounds (hydrogen sulfide, mercaptans, methyl sulfide compounds, and other VOC) at municipal wastewater treatment plants. Furthermore, as the needs of the market have changed, activated carbon technology has also changed, with numerous types of carbons emerging over the years for odor control. Learn more about Jacobi Carbons’ full range of activated carbons for municipal odor control.

PRODUCT GUIDE

FILTRASORB® 820 is a granular activated carbon developed by Calgon Carbon Corporation for the removal of taste and odor compounds, disinfection by-product precursors, and other dissolved organic compounds from potable water

Built on proven BlueInGreen gas dissolution technology, the HyDOZ offers unparalleled advantages for ozonation of water and wastewater. Whether eliminating DBP issues or minimizing the discharge of emerging contaminants, the HyDOZ excels.

Bio-Microbics introduces a new generation of wastewater treatment solutions, the BioBarrier® HSMBR® (High Strength Membrane Bioreactor), to help meet the increasingly stringent needs of specialized applications. The membranes and processes used in this advanced system act as an impenetrable physical barrier for nearly all common pollutants found in wastewater today. The advanced technology offers the highest quality effluent possible on the market. The BioBarrier® MBR was the first system to be approved for water reuse (NSF/ANSI Std 350, class R) by the NSF (National Sanitation Foundation) International.

The influent wastewater is introduced into the shear Enhanced Reactor through the two-phase jet which generates a shear zone in the draft tube. The bacterial agglomerates contained in the sludge are simultaneously disintegrated into small flocs, thus creating a large contact area between the liquid phase and the bacteria.

Granular, powdered and extruded activated carbons for the primary treatment of water, recovery and recirculation of process liquors, and treatment of waste liquid streams. The AquaSorb® range of activated process water treatment carbon is manufactured from coal, coconut shell and wood raw materials through steam or chemical activation. Jacobi Carbons offers a supply of AquaSorb® in a range of granular, extruded (pelletised) and ground powder forms, which are specifically designed for use in the liquid phase adsorption systems. From use in large municipal treatment facilities, to small domestic use cartridges, AquaSorb® is synonymous with high efficiency, extended life and cost-effective solutions.
